Application filed. January 10, 1914. Serial No. 811,457. l

To all whom it may concern:

Be it known that I, JOHN O. DAVISON, a citizen of the United States,residing at Memphis, in the county of Shelby and State of Tennessee,have invented new and useful Improvements in Concrete Construction, ofwhich the following is a specification.

The invention relates to building construction and more particularly tothe class of interlocking concrete construction.

The primary object of the invention is the provision of a concreteconstruction wherein the walls and studding can be readily and easilylocked together, without the use of nails or other fasteners nor thenecessity of the use of tools, thereby avoiding the expense of labor andthe ordinary waste of materials.

Another object of the invention is the provision of a buildingconstruction wherein the same is rendered positively dampproof,fire-proof and practically air-tight and which can be readily razedwithout damage to the materials so that the latter can be again used inerecting edifices thus being practically indestructible.

A further object of the invention is the provision of a buildingconstruction where in the development of an edifice is unlimited, theconcrete sections and studding being interlocked in a novel manner toinsure strength and durability.

A still further object of the invention is the provision of a buildingconstruction which is similar in construction, the parts of which can beconveniently molded and also one which is inexpensive to erect.

\Vith these and other objects in view the invention consists in theconstruction, combination and arrangement of parts as will behereinafter more fully described, illustrated in the accompanyingdrawing forming a part of this application and pointed out in the claimshereunto appended.

In the drawings: Figure 1 is a fragmentary horizontal sectional viewthrough the outer wall and the studding of a building constructed inaccordance with the invention. Fig. 2 is a perspective view of onesection of the studding thereof. Fig. 3 is a sectional view on the line33 of Fig. 1. Fig.4; is a perspective view of the corner studding.

Fig. 5 is a vertical sectional view thereof and showing'the weatherboarding applied. Fig. 6 is a horizontal sectional view of a modifiedform of outer wall and studding.

Fig. 7 is a perspective view of one section of the studding. Fig. 8 is afragmentary vertical sectional view on the line 8-8 of Fig. 6. Fig. 9 isa view similar to Fig. 6 showing a still further modification. Fig. 10is a perspective view of one section of the studding. Fig. 11 is aperspective view of the corner studding.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawing. 1

Referring to the drawings in detail A designates the outer wall and Bthe side studding and G the corner studding, each being constructed in amanner hereinafter more fully described.

The outer wall A is made from the re quired number of weather boards 10each being of the desired length and preferably formed from concretehaving provided on its upper longitudinal edge a tongue 11, while in thelower longitudinal edge is a groove 12 which is correspondingly shapedwith respect to the tongue so as to receive the latter of another boardwhen spaced in position and adjacent thereto, the outer surfaces ofthese boards being inclined as at 13 so as to present the appearance atthe outside of the wall of the ordinary weather boarding.

Formed on the inner face of the board 10 at a medial point thereof is aT-shaped locking rib 14: while at the ends of the said board areL-shaped locking flanges 15 for locking engagement with the studding ina manner presently described. i

The studding comprises a rectangular shaped column which. is made insections 16 formed with a longitudinal center web 17' while in a pair ofthe opposite sides of said sections are medial slots 18 which receiveeither the ribs 14 or the flanges 15. on. the boards 10 for the securingthereof to the studding and also for connecting the boards together inlongitudinal alinement with each other. The remaining pair of sides ofthe section 16 at respective ends thereof are formed with a T-shapedslot and a T- shaped tongue 19 and 20 respectively so that on stackingthe sections upon each other they will be interlocked with one anotherand the boards of the Wall will be united together.

The corner ends of the boards 10 are formed with bevels 21 to assure aclose joint and a sharp corner. Provided on the inner faces of the saidboards 10 spaced from the corner ends are T-shaped ribs 22 for lockingengagement with the corner studding C which comprises a rectangularshaped column made from a plurality of hollow sections 23 formed withslots at in adjacent faces to receive the ribs 22, the ends of thesections 23 being provided with the T-shaped slot and T-shaped tongue atand 26 respectively for the interlocking of the sections togetherthroughout the length of the column. The corner sections 23 are formedwith an abutment shoulder 27 which serves as a back for the lathing orinner walls of the building.

In Figs. 6, 7 and 8 there is shown a modifled form of wall and studdingwherein the boards 28 constituting the wall are each formed withintermediate L-shaped flanges 29 and outer L-shaped flanges 30 forlocking engagement with the side and corner studding. Each side studdingcomprises a hollow column formed from rectangular shaped sections 31having lateral extending corner flanges 32 which are adapted to engagewith either flanges or 30 as shown in Fig. 6 of the drawing so that thestudding will be fastened to the boards 28 in erecting the building. Thecorner studding coinprises a column formed from hollow rec tangularshaped sections 33 provided with laterally extending corner flanges 3stand a triangular shaped corner flange 35 respectively, the flanges 3%being designed to engage in the flanges 30 of the boards 28 while theflanges 35 serve as bearings for the lathing or inner wall of thebuilding. These sections 32 and 33 of the side and corner studding haveformed in each end thereof a T-shaped slot 36 and a T-shaped tongue 37so that the latter on one section will engage in the slot 36 on anothersection adjacent thereto for the interlocking of the same.

In Figs. 9, 10 and 11 there is shown a still further modification ofstudding for the side and corner of the building, the side studdingcomprising a substantially I-shaped beam 38, the flanges 39 of which areadapted to engage the L-shaped flanges 4:0 on the boards-i1 of the wall,the opposite end of the bar v38 being provided with a T-shaped slot 42and a T-shaped tongue 43 so that the sections of the studding willinterlock with each other. The corner studding is made in a plurality ofsections which comprise a straight medial web A with outwardly divergingflanges 45 at the inner and outer longitudinal edges and these flangese5 engage the L-shaped flanges 4.0 on the boards 41 constituting thewall as shown in Fig. 9 of the drawing for the looking of the boards andstudding together, the web as of the section being formed at oppositeends with a T-shaped slot and a T-shaped tongue 46 and a? respectivelywhereby the sections of the studding can be interlocked with each other.

From the foregoing it is thought that the construction and operation ofthe invention will be clearly understood and therefore a more extendedexplanation has been omitted.

What is claimed is 1. In building construction, a plurality of weatherboards, and studding detachably connected to the weather boards and alsoconnecting the latter together, the said studding being formed in aplurality of sections, one end of each section being formed with aT-shaped slot, and a T- shaped tongue at the opposite end of the sectionwhereby the sections of the studding ill be interlocked with each other.

2. In building co istruction, a sectional outer wall, locking ribsformed on the inner faces of the sections of the wall, a studding formedfrom a plurality of sections, the said sections of the studding beingdetachably engaged with the locking ribs, and interlocking connectionsbetween the sections of the studding.

In testimony whereof I affix my signature in the presence of twowitnesses.
